An excellent first attempt Kathy! It is quite difficult to interpret a dream for a stranger when the trigger is not known to the interpreter. Let’s hope that Ethel will respond to this interpretation to see if she can remember the trigger so that you can get another go at it.
Worth noting is that competing in a sport indicates some sort of a conflict situation. When a ball is involved it speaks about words or doctrines. I wonder if Ethel knew what sport it was that they were competing against the country of Botswana?
